Description

A kind of copper coin flying shears control system

Technical field

This utility model relates to a kind of flying shear control system, particularly to a kind of copper coin flying shears control system, belongs to copper coin technical field of processing equipment.

Background technology

nullFlying shear is used to the plate of lateral shear copper coin in copper coin is sheared，So，Basic demand to flying shear is that cutting edge to become to shear and mobile two actions at shearing copper coin part simultaneously，And its cutting edge should be of substantially equal with the rolled piece speed of service in instantaneous component velocity V of plate traffic direction，In the processing procedure cutting synchronization，When cutting，Require that the linear velocity of cutting edge will be with the speed sync of production line，Apply the flying shear control system in copper coin is sheared at present，Flying shear is being driven to realize shear action according to calculating control servomotor used the linear velocity of production line by controller after，This mode control accuracy is low，Error is big，Shear the error between physical length and the design length of copper coin between 1-5mm，Mostly it is between 3-5mm，Have a strong impact on quality and the concordance of product，During also having current flying shear machinery apparatus processing，Selected processing scheme machining accuracy is low，Automaticity is low，Workman's technology is required higher，Inconvenient operation，Labor intensity is high.Have impact on the production efficiency of enterprise to a certain extent, add processing cost.

Summary of the invention

The purpose of this utility model is the drawbacks described above overcoming existing flying shear control system to exist in the application, it is provided that a kind of copper coin flying shears control system.

For realizing the purpose of this utility model, have employed following technical scheme: a kind of copper coin flying shears control system, including the servomotor driving flying shear, flying shear front copper strips transmission line is provided with measurement roller, measure and be provided with rotary encoder one on roller, rotary encoder one is connected to controller, servomotor connects and has rotary encoder two, rotary encoder two is connected to driver, driver is connected to controller, driver is also connected with controlling servomotor, further, described roller of measuring uses in two rollers forming pinch roll on copper strips transmission line, rotary encoder one is set on roller, further, described roller of measuring uses the lower roll forming pinch roll on copper strips transmission line, rotary encoder one is set on lower roll.

Positive Advantageous Effects of the present utility model is: this utility model arranges measurement roller in the controls, use rotary encoder as measuring cell, measure roller employing and rotary encoder reliability height is set on the lower roll of pinch roll, the tachometric survey of transmission line is accurate, the linear velocity that material is long and transmits can be judged accurately, use on servomotor, connect rotary encoder, the speed controlling of servomotor and detection are accurately, it is connected with controller by driver and fetches control servomotor, control accuracy is high, generation without error, the closed loop control that this control system is formed can be by sheared length error control in ± 0.2mm in copper strips cuts, substantially increase shear precision, improve the automaticity of equipment, reduce direct surveillance and operation intensity, effectively improve production line efficiency.

Detailed description of the invention

In order to explain enforcement of the present utility model more fully, it is provided that embodiment of the present utility model.These embodiments are only to elaboration of the present utility model, are not intended to scope of the present utility model.

In conjunction with accompanying drawing explanation further details of to this utility model, accompanying drawing is respectively labeled as: 1: servomotor 2: reductor；3: left reduction box；4: right reduction box；5: upper shears；6: lower scissors；7: lower roll；8: rotary encoder one；9: controller；10: display screen；11: driver；12: rotary encoder two；13: copper coin；14: upper roller.nullAs shown in drawings，A kind of copper coin flying shears control system，Including the servomotor 1 driving flying shear，Flying shear front copper strips transmission line is provided with measurement roller，Measured roller uses and arranges rotary encoder 1 on a roller in two rollers forming pinch roll on copper strips transmission line，Pinch roll is as shown in Figure 2，Upper roller 14 and lower roll 7 constitute pinch roll，More specifically，Described measurement roller uses to form on copper strips transmission line and arranges rotary encoder one on the lower roll 7 of pinch roll，This mode is very reliable accurately，Measure and be provided with rotary encoder 1 on roller，Rotary encoder 1 is connected to controller 9，Servomotor 1 connects and has rotary encoder 2 12，Rotary encoder 2 12 is connected to driver 11，Driver 11 is connected to controller 9，Driver 11 is also connected with controlling servomotor 1.This utility model is operationally, on rotary flying shears, the movement locus of lower scissors is all round, flying shear prestart, upper shears is in position of readiness, the sheet material that measurement roller records is carried out computing by signals such as length and band linear velocities by controller, process, determine whether that providing flying shear starts signal, when being close with setting cut lengths by plate length, controller sends flying shear starting signal and is contacted sheet material by accelerated district, position to any with the shortest time to driver control cutting edge, enter synchronization zone, and synchronized district Tong Bu with sheet material linear velocity a little cut off band to cutting, Fig. 2 midpoint A show and cuts a little, again Tong Bu with sheet material through hypomere synchronization zone to synchronize end point leave sheet material, return to seat in the plane through deceleration area after and put original, wait and shearing next time.nullNative system middle controller keeps cutting Complete Synchronization by double speed principle，Beyond cropped area，In Fig. 2, the region shown in B is for cutting district，Speed can be calculated run，At this moment need not Tong Bu with transmission line，During slitter wheel rotation is turned around，There are two velocity bands，One is retaining zone，Retaining zone can set according to thickness of strip and flying shear parameter，Two is non-retaining zone，In the case of a given cutoff length，Slitter wheel can be run by the rate curve that controller calculates，When processing the speed in asynchronous region，Controller can calculate minimum acceleration and deceleration the most feasible and torque according to cutoff length，When cutoff length is less than when cutting wheel girth，The speed in asynchronous region will be higher than the speed of retaining zone，Otherwise，Then run with the speed less than retaining zone，In asynchronous interval，Speed possibly even drops to zero，Controller is under corresponding charging rate and cutoff length，Do continuous print full closed loop control，It is attached to the update cycle of controller 150 microsecond，Can ensure good to cut precision under very smooth speed，Cut wheel drive actuator and use servomotor,Because controller to ensure to keep closed-loop during the acceleration and deceleration of slitter wheel.Charging actuator uses measures roller detection line speed, can obtain extraordinary effect.

After describing embodiment of the present utility model in detail, one of ordinary skilled in the art is clearly understood that, various change and amendment can carried out under spirit without departing from above-mentioned claim, all any simple modification, equivalent variations and modifications above example made according to technical spirit of the present utility model, belong to the scope of technical solutions of the utility model, and this utility model is also not only restricted to the embodiment of example in description.
